Methamphetamine is not as toxic as some may think. Yes, it does run down your body, but thats mostly due to the fact that most dont eat or drink and neglect their nutrition while high. ITs a serotonin, dopamine, and addrenaline releaser, and also acts as a SSRI (selective serotonin reuptake inhibiter).

The other problem is crack heads make it. As a Biochemical Engineer, production is harmless with no risk of blowing anything up; and the end result is very pure with no harmful leftovers like lithium hydroxide, hydrochloric acid, acetone, ether, etc. Those byproducts that "cooks" dont know are there and dont care to extract are what cause most of the damage. If u mix blood with these things, it destroys the cells and creates black tar-like clumps that can reak havoc in your circulatory system. If its pure, nothing happens and when its over it just wears off; no painful crash. Obviously you cant do it every day or several times a week, but not everyone is weak and cant control themselves like I can; or create the best product ever.

meth realeases Serotonin, which controls small intestine function i.e. cramping in smooth motion to push waste through which is why some get cramps after doing it. It's also responsible for mood regulation as well as starting your sleet cycle, which explains why people dont sleep and get moody when it wears off.

a horrible drug that ruins lives, breaks up families, and does considerable damage to one's looks (its true, look at the before and after pictures). All the people who write definitions promoting it have no idea, and will be o-so-happy when all of their teeth fall out :)

The lonely situation you find yourself in, after using methamphetamine. Typically, broke, with no job, falling apart, stuttering, wondering why you pulled into this parking lot "What the hell was I doing just now?" when all your "new best friends" have left you for better and you feel like it's the end of the world.
